Optimizing the airflow in the casing

post #1 of 12
Thread Starter 
Hi people , I am about to get a new casing(650D) and here is my setup.

2600k
noctua u12p-se mounted vertically
p8p67 evo
ati 6970
3 hdds and 1 ssd

Note : The blue arrow is a 140mm noctua p14 fan. The red ones are also 140mm p14 fan. Below are the following sample ideas that i am deciding on.
Sorry for the amateurish drawing.





i wish to ask which of the following will give a more optimal airflow in the casing ? Thanks.

I was asking a similar question in my thread and what I came up with is the first image you drew. Having the airflow as intake from the front and side panels (if your case has an option for 200mm side fan or 200mm side fan and some 120mm fans, I suggest getting them) blowing air into your case, into your CPU cooler and having the rear and top 2 exhaust fans take that air out seems good.

Number 3 by a far margin. You can look around the forums and see many people recommending top intake, front intake, side intake, with a back for exhaust. If your case has mesh vents that allow air to escape, I don't really see the need to get more exhaust fans than 1 intake. What's most impt is to get the air circulating, 1 intake at the bottom front, (unless it's a crazy CFM fan), just isn't enough.

I would recommend you to go-
Front intake
Side intake
Bottom intake
Top exaust
Back exaust

I would definately refrain from Top INTAKE because heat rises! so its better to exaust it out!

Problems:

With image #1 you will most likely have negative pressure
With image #2 switching the rear fan as intake wont help because all of the air will be sucked right away by the top fan + filter is needed.
With image #3 you will need the cpu cooler being horizontal for it to work properly but now you will need dust filters for the top intake.

Or consider another better flowing case.

You should def. try and get a case with an option for a side fan. This can help cool your motherboard and components really well.

Thanks everyone for the inputs so far.
The new casing is a gift from a friend , so I can't reject it without hurting him lol.

Also my gfx card expels the hot air inside the casing , msi twin frozr is a love and hate thing. It warms up my current lian-li pc-7fnwx casing pretty quickly.

I hear ya there, I own 2 MSI TF2 560Ti

This thread by Ehume will help you out for sure, lots of good info

And some tests I made with my case, aiding CPU temps & Gpu temps at the same time.
